Additional information on my original post:
1) Nothing comes up on caller ID when this person calls in (we were hoping for something that actually said "U.S. Treasury"... but that would have been too easy).
2) This same person has called back multiple times apparently, (I'm just finding this out now from Bookkeeping). When this person called before, s/he repeatedly insisted that we give this information immediately, and stated that "the green book" states that banks have to disclose this information upon request.
The whole thing seems odd to me, which is why I am asking this question and hoping someone wiser/more experienced than I will answer. I certainly don't want to withold information from anyone who needs it from the Treasury, but I am concerned about violations of privacy/confidentiality also. We are scrambling around trying to find an officer to answer the question, but it's lunchtime here, so I'm hoping someone from BOL (I love BOL!) will answer. Thanks so much in advance for any help.
3) In the most recent conversation (which we tried to steer to our Cashier/Controller, but he doesn't know what to do with this call either, so we took a message), the person did provide the account number, date, and amount of the ACH.
Thank you so much, LestieG, for your input. Now, I'm just scrambling around trying to find out if we have a policy against giving out this info by phone!
Your help is much appreciated.
